my invention detached from the housing and arranged with its several parts s aced horizontall in the order in which t ey are assemble and- Fig. 3 is a plan view of the device for simultaneously pressing the packing material upon the shaft and against an abutment.

In the drawings I have used the numerals 5 and 6 to indicate the two parts of a receptacle for packing indicated by the numeral 7. This packing is preferably made of felt as in the form of a ringadapted to encircle the drive shaft 8 of a motor car. The shaft 8 has the common t pe of roller bearings 9- and is enclosed in a ousing 10. The part 5 of the packing receptacle is formed to fit within the outer end of the housin 10. and has a peripheral flange 11 arrange to-abut against the end of said housin Washers 12 and 13 of suitable compressi le material, such as cork, are placed at opposite sides of the flange 11 to prevent leakage. To hold the packing receptacle within the outer end of the housing 10, the usual cap 14 is provided. This cap is adapted to be forclbly pressed on the end of the housing 10 about the shaft 8.

packing receptacle is a sprin member 15 havin a serles of peripheral ngers 16 arrange to embrace the packing 7, and a second series of fingers 17 arranged to slidably engage the inner end surface of the part 6. The series of'fingers 16 and 17 extend obliquely at opposite sides from the central portion of the member 15, but the angle made by the fingers 16 with the plane of the member 15 is greater than the angle between the fingers 17 and said lane.

My eculiar form 0 the member 15 with its series of fingers 16 and 17 constitutes an important feature of this invention. The disc member 15 is preferably out from a so as to action of the ring.

Fitting loosely within the art 6 of the sheet of spring metal, such as brass or a copper alloy, by dieing-out a central aperture for the shaft 8 and slitting the peripherof the disc substantially radially. The a ternate fingers thus formed are merely bent d project from opposite sides of the lsc. In operation, the several parts are held together, as shown inFigure 1, by frictional. engagement of the cap 14 with the housing .10, and the fingers 17 are maintained under spring tension so as to press the packing ring 7 firmly against the inner-end surface of the 'I' part 5. -By reason of the oblique arrangement of the fin ers 16, said fingers under the gers 17, also urge the felt radially inward upon the shaft 8. Simultaneously with the above described operation of. the fingers 16 and 17 portions of the ring 7 are forced between the fingers 16 and interlock therewith to'prevent rotation of said Suflicient .s ace is allowed between the outer'end of 't e fingers 16 and. 17 and inner periphery of the part 6 to permit limited movement of the packing-7 and member 15 in engagement with the shaft 8. This arrangement is advantageous in that even when the shaft becomes worn in its bearings so that lateral movement thereof is permitted, the packing is held infirm contact with.

the shaft and'with the surface of the part 5. Thus, the fingers .17 are allowed to slide upon the inner surface of the part 6. By reason of the resilient nature of the fingers 17, said fingers maintain the packing 7 at all times in firm contact with the shaft and packing receptacle. As all parts of the present invention can be manufactured in simple and rapidly operating machines, the expense of t e device has been reduced to a minimum.

Having described my invention what I claim as new and desire to protect by Letters Patent is:

against the inner surface of one of said cupshaped members, and means adapted to engage one of said cup-shaped members to hold said resilient means in compressed engagement with said packmg ring.
